The corrosion behavior of two stainless steels (UNS S32760 and UNS S31603) for marine
applications has been assessed under liquid-solid impingement conditions in 3.5% NaCl. The
corrosion rate and the amount of material degradation due to corrosion and corrosion effects on
erosion have been determined under various conditions. The three environmental parameters
considered in this study are solid loading, flow velocity and temperature. A full two-level factorial
experimental design method was applied to study the individual effects of each parameter as well as
their interactive contributions to corrosion and the effect of corrosion in erosion-corrosion. From the
analysis, velocity shows the greatest effect on the corrosion rate of both materials, followed by solid
loading, temperature, and interactive effects of temperature-velocity and solid loading-velocity.
However, the most effective contributions to the corrosion effect on erosion, often denoted synergy,
are mainly from velocity, solid loading and the interactive effect of solid loading and velocity. In this
paper, the corrosion behavior of two stainless steels and the mechanisms of material degradation
under different experimental conditions will be discussed.
